How to reduce medical errors 

In this article we will go through 7 common prescribing errors – and how to reduce them.

Prescribing errors are the second most common type of medical error (after communication).

All good doctors are good prescribers. Bad prescribers are dangerous

Why are medication errors important?

Medication errors can have anything from minimal/no to severe effects (including causing or contributing to death, permanent dialysis, loss of limb and blindness). 30% of hospital admissions are due to (or in part due to) prescribing errors.

We will now go through how are medical errors reduced. You need to be aware of and think about all 7 types every day.

1. Wrong dose – how to reduce error

As a prescriber, you should know the dose range for any drug you are giving, and know the one that you want for that patient. You should be careful with the units used, e.g. g, mg, mcg, pcg etc. If you are not sure look it up in the BNF (British National Formulary). This incorporates NICE guidelines.

Does adjustment for CKD, CLD, size or age of patient

E.g. allopurinol should be 100 mg OD, not 300 mg OD, in patients with CKD. Again, if you are not sure, look it up in the BNF.

2. Wrong frequency – how to reduce error

You need to know the correct frequency for the drug you are prescribing. Again, if you are not sure, look it up in the BNF.

3. Wrong length of course – how to reduce error

You need to know the correct duration for the drug you are prescribing. Again, if you are not sure, look it up in the BNF.

4. Wrong drug – how to reduce error

This is primarily a matter of knowledge and experience. But if handwritten prescribing is used where you work, your handwriting is important as well. This is why drug names should always be written in CAPITALS.

5. Known allergy – how to reduce error

Ask the patient, look at hospital and/or GP records. If you are not sure, ring the patients family. Check check check. Unfortunately hospital, GP and pharmacy computers are not linked up. So the absence of a drug allergy on one means nothing.

6. Drug not given, or given more than once – how to reduce error

Check the drug card carefully every day, making sure all the prescribe drugs are being given. Or, if they are not given, has the nurse indicated why not given? It may be important eg antihypertensive not given as BP 80/40 – i.e. you may need to stop or reduce dose of that drug.

7. Illegible writing – how to reduce error

Write neatly, clearly and professionally from a position of knowledge, experience and care. Full stop. Write in CAPITALS if necessary. The drug name should be written in capitals anyway.

Band handwriting is lazy and lethal. It is not funny. Do it properly.

How to write up a drug properly

These are examples of moderately good prescribing.

Hand-written

Note. This is a good drug card. Note dcotor indicating who stopped drug, and why and when.

Computer-generated

Note. This is clearly computer generated. If it was handwritten it should be of the same standard. It is not perfect. Can you see errors? Yes, no capitals and who is prescribing these drugs?

Summary

We have described how are medical errors reduced. We hope it has been helpful.
